Wi-Fi Modules:


Headquartered in Zhangjiang Hitech Park, Espressif Systems (Shanghai) Pte. Ltd. is a fabless semiconductor company providing cutting-edge low power Wi-Fi SoCs and wireless solutions for communications and IoT applications..



ESP-WROOM-02 is a low-power 32-bit MCU Wi-Fi module based on ESP8266 chip, embedded with TCP/IP network stacks, 10-bit ADC, and HSPI/UART/PWM/I2C/I2S interfaces. ESP-WROOM-S2 uses a 2 MB SPI flash connected to HSPI, working as the SDIO/SPI slave with the SPI speed of up to 8 Mbps.

ESP8266 Module can operate in the low power connectivity modes; for instance, if it operates in DTIM10, it only consumes 1.2mW while maintaining a Wi-Fi connection. The module also integrates an SPI flash of 16 Mbits used for storing user programs, data and firmware.

Certificates and Compliances:

  • Wi-Fi Alliance, SRRC, FCC, CE, TELEC, IC & KCC Certified
  • RoHS, Halogen Free, REACH & CFSI Compliant
  • Output Power: +22dBm peak power in FCC certification
  • Small Form Factor

    ESP8266 Module can be easily integrated into space-limited devices due to its small size of only 18mm x 20mm (ESP-WROOM-02) / 16 mm x 23 mm (ESP-WROOM-S2).


    2.ESP-WROOM-32 (Based on ESP32 WiFi + BLE ):

    Powered by Espressiffs most advanced SoC, the ESP-WROOM-32 features high performance, wide range of peripherals, Wi-Fi and Bluetooth radio, which provide a complete solution tailored to advanced IoT applications.

    The ESP-WROOM-32, measuring 25.2mm x 18mm only, contains the ESP32 SoC, flash memory, precision discrete components, and PCB antenna to provide outstanding RF performance in space-constraint applications.The ESP-WROOM-32 schematics and PCB layout are freely available for download and may be used as a design reference for developing fully- customized ESP32-based hardware designs.

    Certificates and Compliances:

    Suitable for commercial application development with a robust 4-layer FCC, CE, IC, TELEC, SRRC & KCC compliant design and wide operating temperature range of -40C to 85C.
